Ok, OK, here we see the difference between theory and practice. Neil is absolutely correct that that is the actual definition of static balancing. However, if you take your tires to a shop and say you want your tires static balanced, what they actually do is move all of the weights to where you cannot see them on the inside or on the inside lip.

<You'll have to forgive me if this seems a little silly... but what exactly
is static balancing wheels/tires? I've only known/seen wheel weights.

The difference between static and dynamic balancing has absolutely nothing
to do with the location of the weights!
Static balancing is done with the tire stationary i.e. STATIC. The tire is
hanging horizontally on the tire-mounting machine and weights are added
until it sits level as indicated by a circular bubble balance. This is
easier and requires less time and handling of the tire and therefore
cheaper.
Dynamic balancing, also called spin balancing, is usually a truer and more
accurate way to find the location and amount of weight needed. Dynamic
balancing is done by spinning the tire on a separate machine, which
determines and displays the out-of-balance points and the amount of weight
needed. The easiest location to add weights is the outside edge of the rim.
If a large amount of weight is needed, the extras are usually clipped to the
inside of the edge of the rim. On some types of alloy wheels there isn't a
lip on which to clip the weight. Peel-and-stick weights are used here
For better appearance on fancy wheels, some service centers may put the
weight only on the inside edge if requested but they may ask for an extra
charge for the extra handling.
